clock − Determine processor time
#include <time.h>
clock_t clock(void);
The clock() function returns an approximation of processor time used by the program.
The value returned is the CPU time used so far as a clock_t; to get the number of seconds used, divide by CLOCKS_PER_SEC.
ANSI C
The C standard allows for arbitrary values at the start of the program; take the difference between the value returned from a call to clock() at the start of the program and the end to get maximum portability.
The times() function call returns more information.
